Most of th internet is SSL now. I understand that ssl encrypts the package and proxy can not see that the header contains .exe Bun the file I tried to download is https://download.mikrotik.com/routeros/ ... winbox.exeThis link should be blocked with a "File extension" rule, but I still can download the file.

The content of the "exe" proxy object is simply "exe" without dot. As in the example.
